Does 64 bit really matter than much?
It does if you want to actually use all that RAM
Or what about if I started off with 32 bit, then did an upgrade of the OS, is that likely to work?
Waste of time.
Either do it or don't.
I've been running RHE 64-bit for a few years now, worked fine first time out of the box.
Never looked back.
